Where is the PERSISTENT file system storage with chrome stored?

Question

When you do webkitRequestFileSystem in window.PERSISTENT option in Google Chrome, where are files written to my file system? I would like to delete the files there, and Chrome interacts with them while I create and debug this application.

Answer 1

For me, at least on Mac OSX, they are stored under /Users/USERNAME/Library/Application Support/Google/Chrome/Default/File System for me. If you use profiles, profile directories will be created instead of Default . However, every source stored in files / folders gets confused in directories with which it will not be easy for you to interact.

You have several options for debugging the file system API:

• Use this extension to view / delete files.
• See tips here: http://updates.html5rocks.com/2011/08/Debugging-the-Filesystem-API This includes viewing saved files very easily using the URL filesystem:
• Release the Playground file system demo ( http://html5-demos.appspot.com/static/filesystem/filer.js/demos/index.html ) to its original state. You can use this to easily browse / rename / delete files / folders.
• Chrome DevTools now has support for the file system API for viewing files stored in the source. To use this, you will need to enable experiments with Developer Tools in about:flags , restart, put the gear in devtools (lower right corner) and enable the "FileSystem" check on the experiment tab.

In Windows XP, it is located here: c:\Documents and Settings\USERNAME\Local Settings\Application Data\Google\Chrome\User Data\Default\File System\ .

On Windows 7, the location is C:\Users\USERNAME\AppData\Local\Google\Chrome\User Data\Default\File System .

It is not very useful to look at it because the file names and dir are confused (but the contents in the files are not changed).

As ebidel wrote, the best way is to use the filesystem: browser filesystem: URLs included in Chrome. Fine! You can get the URL using fs.root.toURL() , where fs is the FileSystem object that you get, for example, from window.webkitRequestFileSystem() .

Answer 3

Just for completeness: on linux, it goes to ~ / .config / google-chrome / Default / File \ System /

Answer 4

It seems that the file system repository is encoded so as not to try to do it for sure. As a result, I wrote a very simple simple file manager, available here . Start any web server (I like mongoose for setting it to 0) and go to /filemanager.html route

Answer 5

I saved a file called log.txt on MAC

This ended up ~ / Library / Application \ Support / Google / Chrome / Default / Storage / ext / panbljeniblfmcakpphmjmmnpcaibipi / def / File \ System / iso / p / 00 /

with file name 00000 and no ext
